Pitfalls in the analysis of low-temperature thermal conductivity of high-Tc cuprates
Yoichi Ando, X. F. Sun, Kouji Segawa
Recently, it was proposed that phonons are specularly reflected below about 0.5 K in ordinary single-crystal samples of high-T_c cuprates, and that the low-temperature thermal cond…
c-Axis Transport and Resistivity Anisotropy of Lightly- to Moderately-Doped La_{2-x}Sr_{x}CuO_{4} Single Crystals: Implications on the Charge Transport Mechanism
Seiki Komiya, Yoichi Ando, X. F. Sun +1
Both the in-plane and the out-of-plane resistivities (ρ_{ab} and ρ_{c}) are measured in high-quality La_{2-x}Sr_{x}CuO_{4} (LSCO) single crystals in the lightly- to moderately-dope…
Novel anisotropy in the superconducting gap structure of Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} probed by quasiparticle heat transport
Yoichi Ando, J. Takeya, Yasushi Abe +2
Since the nature of pairing interactions is manifested in the superconducting gap symmetry, the exact gap structure, particularly any deviation from the simple d_{x^2-y^2} symmetry…
Mobility of the Doped Holes and the Antiferromagnetic Correlations in Underdoped High-T_c Cuprates
Yoichi Ando, A. N. Lavrov, Seiki Komiya +2
The emergence and the evolution of the metallic charge transport in the La_{2-x}Sr_{x}CuO_{4} system from lightly- to optimally-doped samples (x = 0.01 - 0.17) are studied. We demo…
